Purpose: :
A strong correlation has been established between visualand social impairment in nystagmus with the help of visual (VF14)and social function (SF) questionnaires (Pilling et al. BJO2005). So far, the relationship between questionnaires and anobjective clinical evaluation has not been established.The aimof this study was to correlate VF14 and SF questionnaires withdiagnosis and visual acuity.

Methods: :
A questionnaire including questions related to visual(VF14) and social function was given to 108 patients with nystagmus. All affected participants underwent a detailed clinical history,and full dilated eye examination including visual acuity (VA),electrophysiology and eye movement recordings.

Conclusions: :
Visual function and social function are dependenton the type of nystagmus with lowest function recorded in acquirednystagmus. While VF14 discriminated between patients with idiopathicnystagmus and albinism the SF did not show an obvious difference.VF14 is a useful tool in assessment of visual function in nystagmus.
